Application mea March` 10,'A 1922. seriainatmo.

To all whom t may concern.' v p Be it known that I, HENRY C. Rinoa, a citizen of the United States, residing at Kansas City, in the county of Jackson and tate of hlissouri, have invented certain new and useful lmprovements in Cement-Block lf/ach'mes,` of which the following is a specilication. n

This invention relates to cement block molding machines, and has for one of its objects to increase the efficiency and utility of devices of this character.

Another object .of the invention is to provide a device of this charactenhaving means whereby blocks of variousv sizes and forms may be molded on the same' machine.

lilith these and otherfobjects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out drawings illustrative of the preferred embodiment of the invention:- l i 1 Figure 1 is a side. .elevation partly in section.. .f

Fig. 2 is an end elevation. n

Fig. 3 is a section on t ie .line.3-3j of Fig. 1. l

Fig. 4 isa plan view .with the mold frame or box removed. Y t i Fig., 5 is a plan view of the 'mold Lbox illustratingv one arrangement of the division members. Y Y *Y l y Fig. 6 is a transverse section on they line 6-6 of Fig. 1. A.; y. i

Figs. 7 and 8 are perspective views ofthe pallet member withtwo forms of core memY bers. l .t v rlhe improved apparatuscomprises a supporting frame including a platform yor bed portion 10, supporting legs .11?, and connecting rails 12 near the lower 'ends of the legs, the rails having bearings 13 to vsupport transverse shafts 14 and 15. 1 i f.

` rlhe platform portion-*.10 is formed `with a relatively large oblong openingfindicated at `16 in Fig. 4. I'

The leg members 11 at each end of the vframe are connected by transverse portions 1, and the latter connected by a strut or support 18 extending longitudinally of the frame. Stepped at their lower ends in the strut 18 are guide members 19, the latter supported at their upper ends in the platform 10 at each end of the opening 16.

is a follower member 20 having a. pluvrality'of sockets indicatedat 21 in Fig. 4,

the object to be'hereaft'e'r eipl'ained` V The intermediate portions of the shafts 14 and 15 (are preferably vsquare or other form than round as shown, and mounted on the lshaft 14v and rotativeV therewithl are crank arms 22I and 23, in alinementlongitudinally of the shaft, `and lmounted on the shaft 15 and rotative therewith are other Icrank arms 24 land 25, the latter at right angles to each other as represented in Fig. 1.

i I' A link 26 is connected at its ends to the crankpin 27 of the crank arm 23and a pin 28 supported by ears 29 depending from the f follower member- 20, while a similar link itsv ends to the crank pin 31 of the crank arm 24'and a" pin 32 30 is connected at supported by ears 32l depending from the follower member 20. Another link' 33' is connected at its ends by the pins 34 and 35 of theV crank arms 2 2 and 24, as shown.

One ofthe transversal shafts, for instance theshaft 14, is extended at one end to receive an operating lever 36, the latter mounted by a pin 37 to swing laterally to a slight degree on the shaft.,y Formed on the adjacentleg member 11 is a projection orstop which the lever 36V engages to vlock the lever'in its Vlower vposition,"and thus hold the follower member in its elevated or highest position as'i'shown in Figs. .y

- By'this arrangement it will be obvious that when the lever36 is depressed and engaged Vwith the stop; lug 38 the follower member 20 Awill, be'uniformly elevated at both ends and locked in elevated position. `v`Laterally' directed shelves 39 are attached lto theplatform 10 and supported Aby braces 40 inconvenient position to support the detachable vmold units, or the completed moldedblocks, or the like. n

' Be'aringvupon the platform'lO is a pallet memberl41 which also forms the bottom of .the mold'boX, v'and 's formed vwith a plurality of openings corresponding to the core Vmembers by 'whichthe openings through the blocks'are formed and may be varied to any required extent as hereafter explained.

The mold box comprises side members 42 and end members 43, the end members having vdownwardly directed pins 44 which engage in sockets in the pallet 41, to hold the end membersfrom lateral displacement.

The side members 42 are provided with stop lugs 45 at the ends against which the against the adjacent-side member 42, and

slotted at the other end to receive a wedge key 48 bearing against the other side member as shown. By this means the wall mem- 1 Y bers of the-mold box are :firmly bound together and supported upon'the pallet or bottom of the mold box.V

The molded blocks are to bev formed with various shapes of openings therethrough, and a plurality of the pallet members'will be provided with each machine having openings corresponding to the core members by which the openings are formed in the block.

For the purpose of illustration two different arrangements of the core members are shown; In` Figs. 5 and 7 aV set'of cores are shown to form a 'pair of blocks with their inner faces in flat V shape, and their outer faces parallel to the sides of the mold boX and with openings therethrough with the sides of the openings in parallel relation to the faces of the blocks.

The vcore members to form theropenings in the block are represented at 49 in Fig. 7, and are provided with dowel pins, indicated at 50, to enter certain of the sockets 2l in the follower member 20.

InF ig. 8 another set of the coremembers 49 are shownand by providing a plurality of the sockets 2l in the follower member, cores of any required Vform and arrangement ma be supportedon the follower, as will beo vious.

The end vmembers 43 of the mold boX are preferably provided with inwardly directed ribs 5l whereby half channels are formed in the ends of the moldedv blocks, to receive binder portions of the cement in which the blocks are embedded when the walls are built up. Y

rIfhe cores 49 as represented in Fig. 7 are formed with Vrecesses 52 to receive portions of the cement to constitute a binder portion to Yunite the walls of the blocks atone side to strengthen and support them and thus increase their resisting power.

The sides 42 of the mold box are formed with channels 53 centrally thereof, to receive the ends of a dividing member, indicated bydotted lines at 55 in Fig. V5, to form half blocks, the dividing member 55 having ribs indicated at 54 to form cement receiving half channels'in the adjacent ends .of the half blocks.

plying the 'number and arrangement ofthe sockets 2l in the 'follower member, the various form ofthe cores may be easily supported by providing each core with dowelY pins 50 to engage two or more of the sockets. y

The improved device is simple inconstruction, can be inexpensively manufactured of any required material, and operates effectually for the purposes described.V

VThe preferred embodiment ofthe invention is disclosed in the drawings and set forth in the specification, but it will be understood that modification within the scope of the claimed invention may be.made in .lie construction without departing from the principle of the invention' or sacrificing any of its advantages.
